Laser surface cladding of Fe–B–C, Fe–B–Si and Fe–BC–Si–Al–C on plain carbon steel

Effect of Ti Addition on Phase Constitution and Wear Resistance of Fe–B–C Hypereutectic Overlays Produced Using Powder-Wire Composite Arc Welding

“…Comparing the results for ΔrG (1) -ΔrG (7) , the unmelted alloy powders in the welding pool would easily react according to eqs. (4), (7), and (2), and the most likely products are the Fe 3 C, FeB, TiC, and TiB 2 phases.…”

“…[1][2][3][4] The Fe 2 B phase has been shown to be responsible for the superior wear resistance and mechanical properties of these alloys. 5,6) These alloys have been widely used to prepare Fe-B-C overlays on substrates for enhancement of the wear resistance using conventional hard facing techniques, such as the laser cladding, 7) plasma transferred arc welding, 8) and arc welding. 9) Recently, studies have focused on the microstructure and wear resistance of hypoeutectic Fe-B-C alloys.…”

The crack control during laser cladding by adding the stainless steel net in the coating

“…The dendrite in the coating is g(Fe, Ni) with solid solutions of Cr, C, B and Si. The interdendritic eutectic is (Cr, Fe) 7 (C, B) 3 [27,28]. The formation process of Fe30 coating can be described as follows:…”

Development of a hard nano-structured multi-component ceramic coating by laser cladding

“…Laser surface modification [3][4][5], laser cladding [6,7], laser particle injection [8,9] and laser surface alloying of pre-placed powders [10][11][12] are some examples of laser-assisted coating processes that are recently being used for surface modification of various materials.…”

“…The coating exhibited a maximum micro-hardness of 1300 HV 0.3 with high resistance to crack propagation [7]. Manna et al [6] attempted to explore the feasibility of developing an amorphous layer of Fe-B-C, Fe-B-Si and Fe-BC-Si-Al-C on AISI 1010 steel by laser surface cladding for enhanced hardness and wear resistance of the substrate. The resultant specimens exhibited excellent wear resistance with micro-hardness up to 1150 HV 0.3 .…”
